Per ESPN, Marshawn Lynch is "not planning to play football again" and the team has "moved on" from the 33-year-old running back.
Lynch first retired after the 2015 season, but returned in 2017 and spent two seasons with the Raiders. Last season he played in only six games before missing the rest of the year with a groin injury.
A five-time Pro Bowler, Lynch finishes his career 29th on the all-time NFL rushing list with 10,379 and 16th all-time in rushing touchdowns with 84.
